You should not expect to see a consistent index signal from 5i25.encoder.index-input as this is simply the real time index input state. Since this is only sampled at the servo thread rate and the index pulse can be much shorter than the thread period, you may only see this occasionally when moving at medium to high speeds To test index operation, you can "sets" the index-enable signal (not pin) manually and see if the signal gets cleared at the index position. > > > ----------------------------- > Regards / Groete > > Marius D.
